SYNTAX ZX80 was a monthly newsletter published in the 1980's
originally for the Sinclair ZX80 computer and then expanded to cover
subsequent computers made by Sinclair (the ZX81) and then later Timex
(the TS1000, TS1500 and TS2068).
It was published by Kirtland H. Olson
of The Harvard Group. It featured reviews, hardware and software
how-tos, news, program listings, editorials, reader-contributed
information and classifieds.
